BACKGROUND

A wide-bandwidth data frame is a frame to be transmitted over awide-bandwidth channel.

The wide-bandwidth channel may include two or more channels. The two ormore channels may be contiguous in frequency or may be separated. Thewide-bandwidth channel may be created using channel bonding to join thetwo or more channels.

The wide-bandwidth channel may achieve higher bit rate, e.g., byoperating in wider bandwidths.

In some demonstrative embodiments, the wide-bandwidth indication may berepresented by one or more bits of the control PHY header of the RTSframe.

In some demonstrative embodiments, the control PHY header may include aplurality of fields, e.g., as follows:

TABLE 1 Number of Starting Field name bits bit Description Reserved 1 0Set to 0 (differential detector initialization). Scrambler 4 1 BitsX1-X4 of the initial scrambler state. Initialization Length 10 5 Numberof data octets in the PSDU. Range 14-1023 Packet Type 1 15 As defined inTable 21-17 (SC header fields). Training Length 5 16 Length of thetraining field. The use of this field is defined in 21.10.2.2.3 (BRPpacket header fields). Turnaround 1 21 As defined in Table 21-1(TXVECTOR and RXVECTOR parameters).

In some demonstrative embodiments, each combination of the 4combinations may indicate at least one channel, for example, in additionto a channel used by a Personal Basic Service Set Coordination Point(PCP) (“the PCP channel”), e.g., channel 1.

In one example, a first combination of the two scrambler initializationbits, e.g., “00”, may indicate a combination of channel 2 in addition tochannel 1, e.g., channels 1+2, a second combination of the two scramblerinitialization bits, e.g., “01”, may indicate a combination of channel 2and channel 3 in addition to channel 1, e.g., channels 1+2+3, a thirdcombination of the two scrambler initialization bits, e.g., “10”, mayindicate a combination of channel 3 in addition to channel 1, e.g.,channels 1+3, and a fourth combination of the two scramblerinitialization bits, e.g., “11”, may indicate a combination of channel 4in addition to channel 1, e.g., channels 1+4. In other embodiments, thetwo bits of the scrambler initialization bits in the PHY header of Table1 may include any other values to indicate any other combination ofchannels.

Inanother example, any other bits may be used to indicate the channels.

Using the three LDPC bits may slightly increase a packet errorrate of wide-bandwidth data frame 111. Devices 102 and/or 140 may setthe three LDPC bits to zero, e.g., when decoding wide-bandwidth dataframe 111, and may set a bit corresponding to a mmWave channel to one toindicate the mmWave channel is being used.
